I'm waiting on new 16s and 315/75/16 duractracs to arrive for my '13 jku 6spd. I know using a procal to set the new shift points is important for an auto trans with bigger tires, but what about for a manual? All that should be off if I don't reprogram is my speedo and the in dash mpg calculator correct? Nothing crucial to the way it will drive? I'll probably buy one anyway, but just wondering if I can let it slide for a bit now.

The only other thing I can think of is are you going to be reusing your TPMS sensors on the new wheels? If you are not, then the ProCal can set the "low" alarm to 0 psi so you can go without them and not be aggravated.

Good call. The new setup is coming with the TPMS's in them so no worries there.

Your odometer will be off too. Be mindful so as not to overstretch oil changes etc depending on how long you wait

Didn't even think of this but that will be helpful. Guess I'll get it sooner than later

ProCal

I don't think the Pro Cals work with the 12's and 13's yet. Look into the Superchips FlashCal. They cost the same and the FlashCal works with the 2013.

Procal works with the 12 an 13's

I have the Procal for my 2013. I set the tire size for the speedo and shift points, turned my TPMS off and added day time runnung lights. So it does wotk with the 2012-13's.

Thanks for the confirmation

I bought it right from AEV to make sure it was the latest one, the DRL, tire size and TPMS work 100%.

Your tires turn 602 revs per mile. Using the formula of 63360 divided by 602 and then 3.14 gives you a calculated tire height of 33.5. The procal will allow you to set tire height to that and both speedometer and odometer will be right on.
